Noise reducing valve for toilet systems

ABSTRACT

The components used in this invention has never been utilized in this special type of arrangement ever before. This new “Noise Reducing Valve for Toilet Systems” does not exist and cannot be found anywhere. 
     Once available to the public it will be very useful and will help many light sleeper to have a better change of getting a good sleep at night, as they will not have to listen to loud toilet noises at night, on whenever they take a sleep.

BACKGROUND OF THE INVENTION

A common problem when using a toilet is the loud noise level that comes from the unit after the flushing. This noise is so loud and even embarrassing, that during late hours of the night when people are enjoying their sleep time, it will awake many light sleepers and specially babies.

Once a person awakes at night it will take them some time to go back to deep sleep or in some cases this will not even be possible as some people have difficulties falling sleep again.

I personally have experienced the need to use my toilet more than once at night, and after flushing it, my wife had awaken and later was difficult for her to go back to deep sleep. To make matters worse the next morning she was tired and sleepy, but still needed to go to work.

I believe this noise problem can be fixed, so people can rest better without having to be awakened by noisy toilets.

All the above motivated me to find a solution and to help others with this common problem that we all suffer.

BRIEF SUMMARY OF THE INVENTION

After giving it much thought and inspecting several brands of Toilet-Tank systems, I was able to identify where the noise was coming during the flushing.

The problem came when the water in the tank reservoir went through the inner pipe that connects the Tank to the Toilet Bowl. Here the water had to do a sudden and rapid 90 degrees (approx) change of direction after colliding with the top backside of the toilet bowl, on his way down to the bowl and to the drain.

I realized that by changing the direction of the water in a more gradual way, it would reduce most of the noise created at this point. What I needed was a new valve that would reduce the noise level by changing the direction of the water gradually instead of suddenly, and after making several prototypes, I was able to come up with the “Silencer Valve”, which I have successfully designed, installed and tried in my toilet.

DETAILED DESCRIPTION OF THE INVENTION

The most common system found in the bathroom of a house is the two-piece tank toilet system, where the tank is situated above the toilet.

There are many different brands, models and variations of tank and toilet systems, but most of them are very much alike with slight differences. For this particular case, I am using an American Standard, Plebe model.

The tank is the place where the flushing water is stored, and here is where we find two very common valves:

-   -   The Fill Valve, and the     -   Flush Valve

After pushing down the Flush handle FIG. A (2), the Flapper (4) of the Flush Valve, opens and lets the water rush down the bottom tube of this valve into the Toilet Inlet (13), and here is where a lot of noise is produced.

After the water from the tank (1) gets inside the Toilet Inlet (13) it starts to whirls around the bowl and finally exits through the Toilet drain (11).

The idea behind this invention is to reduce the noise produced by this flushing action, and because most of the noise is made when the water is traveling from the tank (1) to the drain (11), here is where something needed to be interfaced, in order to reduce the noise.

I devised a way to minimize the sound made by the water, and it is basically to change the angle and speed in which the water travels from the tank to the toilet, by using a Silencer Valve (8) located at the bottom of the Flush Valve pipe (12) and the Toilet Inlet (13).

This Silencer Valve has to be easy to install and remove so any person could install it with easiness and quickness, in their existing Toilet-Tank systems.

In the FIG. (1) where the Silencer is Shown, we can see that this unit has two main components. The Cylindrical body (A) and a Flat Angle piece (Flat Slider) (B).

The Cylindrical body has the purpose This Silencer Valve has to be easy to install and remove so any person could install it with easiness and quickness, in their existing Toilet-Tank systems.

In the Picture (1) where the Silencer Valve is shown, we can see that this unit has two main components. The cylindrical body to hold the Flat Angle piece in place and at the right position. It also makes the installation of this valve very fast and easy. In the present example, the inner diameter of the bottom pipe of the Flush Valve is 2 inches (this is the most common size for this valves), so in order to have a good fit; the outside diameter of the Silencer Valve is about 15/16 inches.

It has to be located inside and under the bottom of the Flush Valve water outlet window (see FIG. 2). The direction of the Slider has to be opposite to the bowl (or towards the wall behind the tank).

The total height of this valve is 3 3/16 inches (or the distance from the lower edge of Flush Valve water window, to the bottom of the toilet inlet).

The Flat Slider (B) is solidly connected to the cylindrical body at about ½ from the bottom, and goes all the way down to the Toilet inlet (13) in an angle of about 40-50 degrees. Depending on the angle, the water is slowed more, or less, and the sound level of the water is also reduced accordingly.

For an angle of 40, it was found that the water sound level went from 74/68 dB (74 dB is the average sound level during flushing, and 68 dB is the sound level of the last 0.5 sec) to 55/68 dB (the experiment was conducted with the water inlet shut off, in order to separate the noise generated from the Filling Valve).

The measurements were taken with the toilet lids open and at a distance of 3 feet of distance from the toilet bowl.

The Tank at the time of the experiment had a capacity of 2.3 gallons of water.

For this experiment, it was used a Radio Shack Digital Sound Meter model 33-2055, with sound capture range of 50-126 dB. The experiment was successful.

This is a very simple but effective way to drastically reduce the noise level created during the flushing of a toilet. There are some side effects as a lower speed of the water during flushing, but under normal use, the toilet continues to work as usual.
